Its three lowest-scoring questions, and what the evidence didn't show.
Humble Bundle publishes no standalone emissions data.
Humble Bundle's supply chain consists primarily of software licensing agreements with game developers, cloud hosting, and payment processing — an inherently short, low-material, digital supply chain with no physical goods manufacturing or shipping.
No Humble Bundle-specific multi-year emissions trajectory exists.
